Hi Everyone,
I have been on Spring Break, so it has been awhile since I posted. I know some of you are getting ready to do your frog dissection and are cringing in anticipation. I thought I might share three good sites which will help you with this lab:
http://www.froguts.com/flash_content/index.html
http://frog.edschool.virginia.edu/
http://www.biologycorner.com/worksheets/frog-dissection.html
The first two sites provide virtual frog dissections which can be used to practice before you do the real thing and the last site gives an easy to follow frog dissection procedure.
Hope that helps you tackle the frog project. I am off to my last weekend of golf before we resume classes Monday :-)
God Bless,
Steve

We got to see Jay Wile at the APACHE homeschool convention this weekend. My husband and I really enjoyed his talks.

Jay Wile is a great speaker and a wonderful man. He has taught me much. I would not be in the place I am if it were not for his mentorship. I work for him at Apologia because he is the real deal: a Christian man with a big heart. He is worthy of your support and you can trust what he says as factual and true.
God Bless,
Steve

I have been using Apologia curriculum for 6 years. Obviously, I'm happy with it. I've also heard Jay Wile speak on several occasions. In fact, I always make it a point to attend his workshops at the homeschool conference, and it's always worth my time. Glad to know he's big hearted too.

Hi Everyone,
Sorry I have not been able to comment here for a few days, but Potter's School is in the midst of registering students for next year and I had 139 registrations for my classes to process the first two days. I only take 180 per year so I am well on my way.
Anyway, I am glad you all have such glowing opinions of Apologia books. I have been working for Apologia now for six years, and I just love my job. If you read my bio online, you know that I have been a medical technologist, research chemist, and public school teacher prior to coming to work for Apologia. Apologia is a family run business and they made me feel like one of the clan right from the start. I can't think of anything I would rather be doing than teaching kids through Potter's School for Apologia. It is a GREAT job and I plan on doing it until I retire, Lord willing. Jay Wile is a great boss and I just love the man.
I had better get back to grading and lesson planning. For those of you doing Module 14, 1st half, of General Science here is my recorded lecture over the circulatory system and my notes. It may take a minute to download.
Module 14, Part 1
Hope you enjoy listening and following along.
God bless,
Steve

Opps. Many of you have written wondering if I video recorded the presentation for GS Module 14-1. The answer is, "Yes." You will find it linked to my web page: just click on "Recorded General Science," then click on "Class Video Example."
God Bless,
Steve

Hi Everyone,
For those of you doing Apologia Marine Biology, here is a great little vignette for Module 14:
Life, as most people understand it, is driven by the sun, but deep sea organisms have no access to sunlight, so they must depend on nutrients found in the dusty chemical deposits and hydrothermal fluids they live in. Previously, marine biologists assumed that vent organisms were dependent on a "rain" of detritus from the upper levels of the ocean, like deep sea organisms are. This would leave them dependent on plant life and thus the sun. Some hydrothermal vent organisms do consume this "rain," but with only such a system, life forms would be very sparse. Compared to the surrounding sea floor, however, hydrothermal vent zones have a density of organisms 10,000 to 100,000 times greater.
Hydrothermal vent communities are able to sustain such vast amounts of life because vent organisms depend on chemosynthetic bacteria for food. The water that comes out of the hydrothermal vent is rich in dissolved minerals and supports a large population of chemoautotrophic bacteria. These bacteria use sulfur compounds, particularly hydrogen sulfide, a chemical highly toxic to most known organisms, to produce organic material through the process of chemosynthesis.
The ecosystem so formed is reliant upon the continued existence of the hydrothermal vent field as the primary source of energy, which differs from most surface life on Earth which is based on solar energy. However, although it is often said that these communities exist independently of the sun, some of the organisms are actually dependent upon oxygen produced by photosynthetic organisms. Others are anaerobic.
The chemosynthetic bacteria grow into a thick mat which attracts other organisms such as amphipods and copepods which graze upon the bacteria directly. Larger organisms such as snails, shrimp, crabs, tube worms, fish, and octopuses form a food chain of predator and prey relationships above the primary consumers. The main families of organisms found around sea-floor vents are annelids, pogonophorans, gastropods, and crustaceans, with large bivalves, vestimentiferan worms, and "eyeless" shrimp making up the bulk of non-microbial organisms.
Here is a great web site to view the ceatures that live near the hydrothermal vents: http://people.whitman.edu/~yancey/vents.html
Have fun looking at these amazing creatures that live in the deepest parts of God's oceans.
God Bless,
Steve

Hi Everyone,
For those of you slugging your way through Apologia General Science, Module 15, I though you might like this little vignette on the urinary system:
The main task of the kidneys is to clean blood. Unlike the lymph nodes which clean lymph, the kidneys clean the blood and blood plasma. This is important because the lymph system cannot clean the way that the kidneys clean. The lymph system cleans out organisms and chemicals that it recognizes as disease-causing. The kidneys do something completely different. They clean out chemicals that are not dangerous to the body until they reach certain levels. Thus, the chemicals are not necessarily ones that cause disease. Instead, they are simply chemicals whose levels in the blood must be monitored and maintained. Each nephron in the kidneys is a tiny filter which empties into a tiny, curving tubule. Each nephron works independently to make urine of the others. It takes only five minutes for your kidneys to process all of the blood in your body, which means that it filters all the blood in your body 288 time each day, 105,120 times each year, or 8,409,600 times in an 80 year lifespan. Any water and chemicals that were not reabsorbed into the blood go from the nephrons into the renal pelvis and flow out of the kidney to the ureter. At this point, the mixture of water and chemicals is called urine. The urine travels through the ureter and is held in the bladder. Eventually, the bladder releases the urine it has stored, and the urine leaves the body through the urethra. About 150 liters (33 gallons) of fluid pass through your kidneys every day during the 288 filtrations. But 99% of this is cleaned and goes back into your blood stream. The remaining 1% makes up our daily urine volume. In an average lifetime, humans pass about 40,000 liters (8,800 gallons) of urine out of their bodies. This is enough to fill 500 bath tubs. The kidneys are about the size of a 3" X 5" index card. The best dialysis machine on the market today is about the size of a small refrigerator.
If you believe in evolution, then you have to believe that the amazing filtering capacity of the human kidney just happen by random chance. It is just a freak of nature that your kidneys filter your blood so faithfully day in and day out. I think not. Time and time again when we look at nature, we see the hand of the Master Craftsman. Only someone as wise as God could ever design something as unique as the human kidney.
Here is a great web site for you:

God Bless,
Steve

Hi Everyone,
I am in the middle of final exam season right now, so this week's vignette will be short and sweet. For those of you doing Apologia Biology, here is the link to my class recording for the first half of Module 16. I am sure you will find the information on snakes, lizards, dinosaurs, and web pages shown enlightening. Sorry that I could not be more helpful this week, but I have 186 exams to grade.
Here is that link: Module 16-1 You can adjust the size of the viewing window by simply pressing "Ctrl" and minus (-) to make the window smaller or "Ctrl" and plus (+) to make the window larger to fit you screen.
God Bless,
Steve
